CLARENCE C. KORNS, OF J OHNSTOWVN PENNSYLVANIA, ASSIGNOR TO THE LORAINSTEEL COMPANY, A CORPORATION OF PENNSYLVANIA.

HOLDING DEVICE FOR SWITCH POINTS OR TONGUES.

SPECIFICATION forming part of Letters Patent No. 784,689, dated March14, 1905.

Application filed October 5, 1903. Serial No. 175,825.

To 1072 0777 it may concern:

Be it known that I, CLARENCE C. KORNS, of J ohnstown, in the county ofCambria and State of Pennsylvania, have invented a new and usefulImprovement in Holding Devices for Switch Points or Tongues, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, which form a part of this speci- IOfication.

My invention has relation to holding devices for switch points ortongues, and is designed to provide a simple and effective device whichcan be readily attached to the 5 tongue or point and which while it doesnot form a positive lock for the tongue, which can be thrown by means ofthe usual switchbar, acts to prevent accidental displacement thereof.

Vith this object in view my invention consists in the novelconstruction, arrangement, and combination of parts, all as hereinafterdescribed, and pointed out in the appended claim, reference being had tothe accompany- 5 ing drawings, in which Figure 1 is a plan view of aswitch embodying my invention with the cover of the attached box orcasing removed; Fig. 2, a section on the line 2 2 of Fig. 1, and Figs. 3and 3 1 detail views of the weight.

The letter A designates the body portion or casting of the switchstructure, and B the movable tongue or point. The latter is formed Witha depending lug b, to which is secured one end portion ofalaterally-projecting arm or rod C.

D is a small weight, having formed thereon or attached thereto the twostuds (Z and (if. The downwardly-bent end portion of the arm or rod C ispivotally engaged with the stud (Z, 4 and the stud (Z' is journaled in alug E of an inclosing 190); F.

WVhen the switch is moved from one side to the other by means of theusual switch-bar, this weight is thrown over from one side to the lotherabout the center (Z, its holding effect being sufficient to preventaccidental movement of the tongue. To prevent the weight from fallingtoo low, it is provided with the stop lugs or projections (Z A bushing 5or sleeve G is secured between the lug 7) and the jam-nuts g in order togive the tongue an operating connection with the rod or arm C in thatdirection.

1 do not wish to limit myself to the precise construction andarrangement of parts herein shown and described, as changes may be madein the details thereof without departing from my invention as defined inand by the following claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is I The combination with a movable switchtongue or point, of a pivoted weight, an arm 5 connected to'the tongueand pivoted to said weight eccentrically of the pivotof the latter, andmeans for always holding the weight in a position in which the pivotalconnection of the said arm therewith is above its own pivot, 7 wherebythe throw of the switch-tongue will act to throw said weight.

In testimony whereof I afliX my signature in presence of two witnesses.

CLARENCE C. KORNS.
